RICHARD BEATTY FITHIAN AND JOHN ADAMS WYMAN, OF NEW YORK, N. Y.

SEWER OR SEWER-PIPE.

SPECIFICATION forming part of Letters Patent No. 439,644, dated November 4, 1890.

Application filed July 24,1886- Serial No. 209,005. (No model.)

To aZZ whom it may concern.-

7 Be it known that we, RICHARD BEATTY FITHIAN and J OHN ADAMS WYMAN, of New York city, in the county and State of New York, have invented certain new and useful sewage; and it consists in the improved construction and arrangement or combination of parts hereinafter fully disclosed in the description, drawings, and claims.

The objects of our invention are, first, to provide means for deflecting the thick and solid sewage to a tank and for straining all solid matter from the thin and fluid sewage; second, to provide means for deflecting the thick and solid sewage into a tank and for receiving the overflow under a heavy flow of sewage and straining or filtering the same; third, to provide means for preventing eddies or backfiow in the deflected branch pipe; fourth, to provide means for skimming off the light solid sewage in the filter-box, and, fifth, to provide means for straining or filtering the sewage in the filter-box. These objects we attain by the apparatus or device illustrated in the accompanying drawings, forming part of this specification, in which the same refererence-numerals indicate the same parts, and in Which- Figure 1 represents a horizontal section of a sewer-pipe, the receiving-tank, the deflecting-pipe for the same, the filter-box, and pipes pertaining to the same; Fig. 2, a longitudinal vertical section of a portion of the filter-box; Fig. 3, a longitudinal vertical section of the sewerpipe and deflecting-plate Fig.4, a transverse section of the filter-box; Fig. 5, a section al detail view of the filter; Fig. 6, an edge View of the deflector, and Fig. 7 a front view of the same.

In the drawings, the numeral 1 indicates the sewer-pipe, which is of the usual or of any desired construction, and which enters one end of the filter-box 2, which has an outletpipe 3 at the opposite end. The deflectinglpipe or branch pipe 4 enters the side of the sewer-pipe near its entrance into the filterbox, and a curved straining or deflecting plate 5 slides in vertical grooves 6 in the sides of the sewer-pipe at the mouth of said branch pipe, deflecting the solid sewage into the same. The lower portion 7 of this deflecting-plate 5 is solid and the upper portion Sis perforated, and said solid portion may be sunk into a groove or recess 9 in the bottom of the sewerpipe. A ledge or flange 10, which forms a con tinuation of the side of the sewer-pipe, projects into and partly across the mouth of the branch pipe and serves to prevent eddies or backflow in the sewer-pipe. The branch pipe extends to a tank 11 for the reception of the solid sewage.

The filter-box 2 has a filter 12 secured near its end and oblique to its sides, and said filter is formed of frames 13, hinged together and having perforations 14. Suitable straining or filtering cloth 15 is placed between said hinged frames and clamped between them, as shown in Fig. 5 of the drawings, and the frames are supported in ways 16 in the sides of the filterboX. The filter 12 is placed oblique to the sides of the box 2, and the side forming the ,acute angle between it and the filter has an opening 17 near or at the top of the box, over which opening a gate 18 slides in flanged vertical ways 19. An arm 20 is pivoted to the filter and has a float 21 adjustably secured upon its outer free portion, and a stud 22, which projects upward and inward from said gate 18, is pivoted in said arm near its inner pivoted end, so that the gate may be vertically slid by rocking said arm. Apipe 23 extends from the opening 17 in the side of the filter-box to the tank 11.

The filter-box is provided with a suitable man-hole 24 for cleaning or repairing it, and may havea suitable outlet or tap 25 in the bottom for draining it. Under a normal flow of sewage the deflecting-plate 5 is raised so as to bring the solid portion 7 of the same to a suitable height for deflecting the solid sewage into the branch pipe 4, while the thin sewage may flow through the perforated portion into the filter-box, where it will be sufficiently retarded in its progress, on account of the larger diameter of said box, to allow the lighter particles to float on top and to be deflected by the oblique filter 12 into the shallow opening 17, which will at all times be kept slightly below the level of the sewage in the tank by the arm, float, and stud. The water will pass through the filter 12, while the solid sewage will either be carried off through the opening 17 and pipe 23 to the tank 11, if it is sufliciently light to float, or it may sink to the bottom of the filter-box and be removed therefrom in any suitable manner.

If a heavy flow of sewage occurs-such as a flow caused by a heavy rainthe deflectingplate is depressed so as to present only the perforated portion, and the thin sewage will flow freely through the same and be strained or filtered in the filter-box, while the coarser sewage will be deflected into the tank.

Various modifications may be made in the deflecting-plate, in the filter, and in other parts of the apparatus or device without departing from the spirit of our invention.

Having thus fully described the construction and arrangement or combination of the several parts of our improved device for collecting solid sewage, its operation, and advantages, what we claim as new is 1. The combination of a sewer-pipe, a perforated deflecting-plate in the same, a branch pipe in front of said deflecting'plate, and a filtering-tank at the rear of said plate and provided with means for separating the solid and fluid sewage, substantially as described.

2. The combination of a sewer-pipe, a vertically-adjustable deflecting-plate having a solid lower and a perforated upper portion, a

branch pipe in front of said deflecting-plate, 35 and a filtering-tank at the rear of said plate and provided with means for separating the solid and fluid sewage, substantially as de scribed.

3. The combination of the sewer-pipe 1, having vertical grooves 6 and a recess 9 in its bottom, the curved deflecting-plate 5, having the solid lower portion 7 and the perforated upper portion 8 and sliding adj ustably in said grooves 6, the branch pipe 4, and the filteringbox 2, having the filter 12, substantially as described.

4. The combination of the sewer-pipe l, the branch pipe 4, the deflecting-plate 5, and the ledge or flange 10, substantially as described. 59

5. The combination of the filter-box 2,11aving the opening 17 and vertical flanged ways 19, the oblique filter 12, the pipe 23, the gate 18, sliding in said ways 19 and having stud 22, and the arm 20, having the adjustable float 5 5 21, substantially as described.

6. The combination of the sewer-pipe 1, the curved deflecting-plate 5, the branch pipe 4, the tank 11, the filter-box 2, having outletpipe 3, the oblique filter 12, the pipe 23, and 60 the gate 18, and float-arm 2O 21, substantially as described.
